Methodology of Unequally Spaced Frequency Allocation for WDM Transmission Systems Using Typical Dispersion-Shifted Fiber Cable

摘要

The transmission performance of WDM trans- mission systems is influenced by many effects according to the type of optical fiber employed in the system. Japanese high- speed transmission systems use dispersion-shifted fiber (DSF). It is well known that the transmission distance of WDM systems employign DSF is restricted by fiber four-wave mixing (FWM). Unequally spaced channel allocation (USCA) was proposed to Mitigate the FWM effect.
